Efficacy of endobronchial intubation with double-lumen tube using fiberoptic bronchoscope assisted by video laryngoscope / 中华麻醉学杂志

ABSTRACT

Objective To evaluate the efficacy of endobronchial intubation with double-lumen tube using fiberoptic bronchoscope assisted by video laryngoscope.Methods Thirty patients of both sexes,who underwent failed endobronchial intubation with double-lumen tube using direct laryngoscope,aged 25-64 yr,with body mass index of 23-34 kg/m2,were randomly divided into 2 groups (n=15 each) using a random number tablefiberoptic bronchoscope group (group F) and fiberoptic bronchoscope assisted by video laryngoscope group (group VF).The patients were intubated with double-lumen tube under the guide of fiberoptic bronchoscope in group F.The patients were intubated with double-lumen tube under the guide of fiberoptic bronchoscope assisted by video laryngoscope in group VF.The rate of successful intubation,intubation time,and glottis and epiglottis exposure condition when the video laryngoscope was used in group VF were recorded.The patients were followed up postoperatively,and the development of intubation-related complications (sore throat,hoarseness and swallowing difficulty) was also recorded.Results Compared with group F,the intubation time was significantly shortened,and the success rate of intubation at first attempt and second success rate of intubation were significantly increased in group VF (P＜0.05).There was no statistically significant difference in the incidence of intubation-related complications between the two groups (P＞0.05).Conclusion Video laryngoscope provides better efficacy for endobronchial intubation with double-lumen tube using fiberoptic bronchoscope.
